gear05 contains a single cog30. For each degree cog30 rotates, the door will translate in the Y axis. If we calculate the circumference of cog30 and divide by 360°, we'll know how much to translate the door in the Y axis.

Here's a quick breakdown of this process (Fig.35):

1. Rotating cog30 360° will translate door the same distance as the circumference of cog30.
2. Therefore, we can assume that by rotating cog30 1°, door will translate circumference/360.

The circumference of a circle is calculated as: 2? * radius

Where ? (Pi) = 3.14159, the circumference of cog30 is:

= 2? * radius
= (2*3.14159)*15
= 94.248

Therefore, rotating gear05 by 1° will translate door:

= 94.248/360°
= 0.2618

Rotating gear05 by 90° will translate door:

=90*0.2618
